+# Sentry Tutorial 
+[Sentry](https://sentry.io/) provides error monitoring for production. LiteLLM can add breadcrumbs and send exceptions to Sentry with this integration
+
+This works on normal, async and streaming completion calls
+
+### usage 
+
+```python
+import litellm
+from litellm import completion 
+litellm.set_verbose = True
+
+litellm.input_callback=["sentry"] # adds sentry breadcrumbing
+litellm.failure_callback=["sentry"] # [OPTIONAL] if you want litellm to capture -> send exception to sentry
+
+import os 
+os.environ["SENTRY_API_URL"] = "your-sentry-url"
+os.environ["OPENAI_API_KEY"] = "your-openai-key"
+
+# set bad key to trigger error 
+api_key="bad-key"
+response = completion(model="gpt-3.5-turbo", messages=[{"role": "user", "content": "Hey!"}], stream=True, api_key=api_key)
+
+print(response)
+```
+
+[Let us know](https://github.com/BerriAI/litellm/issues/new?assignees=&labels=enhancement&projects=&template=feature_request.yml&title=%5BFeature%5D%3A+) if you need any additional options from Sentry.
